Okay so I've gotten to the very end of this quest and even killed Vaemina, then I would either got to my inventory while its automatically saving or try and save myself and the game crashes >_< I've played the same quest Six times. I play on an X-box and Skyrim came with it for free, so it's kind of awkward when I think oh maybe the disk needs to be cleaned lol. Has anyone else had this saving and menu thing happen to them? I'm about to play it for the 7th time and hopefully I can save once I get out of this place. If not then I guess I'm making a new character, which is not fun for me haha, I hate doing all that work and having a really big inventory with nice weapons and a fat wallet and thenstarting from the beginning.

Once you drink the torpor you have to wait until you exit the temple before saving.

The bug is being addressed in the 1.9 patch.

Turn off all autosaves after you drink the Torpor, that way you can still access you inventory without fear of an autosave triggering.
I had this too recently.

Aw thanks didn't know you could do that, I'm definitely going to since I just went into my inventory again and the game crashed again, 8 times the charm right?
Edit: Apparently not >_< Luckily It did save up so I don't have to run and get the book and potion.
